I took a Shinkansen train from Osaka to Fukuyama, and rented a car there to make a trip along Shimanami Kaido Highway. From Onomichi, I had drove through Mukojima, Innoshima, Ikuchijima, Omishima, Hakatajima, and Oshima Islands, and was going to "land" Shikoku Island. I could overlook much of the route on the top of the observatory. But the road to there was a narrow one, and, for my surprise, I had to pass a big tour coach on the way. So, please be careful when you drive or cycle.
